RE: PowerEdge 1950 with failed MY412 card
The WX072 controller cards are Perc 5/i's. Did they also include the battery, holder and cable? Did they come with a memory DIMM on the board?
The cable is the same. It attaches to the controller on port closest to the front. Here is a link to the cable routing information for either the SAS 5/i or the Perc 5/i , page 56 and following: http://en.community.dell.com/support-forums/servers/f/906/t/19540862/reply.aspx
Also, if you have installed the Perc 5/i, enter the Ctrl R bios to set up your RAID array. Spiceworks has an excellent tutorial on setting up an array on the Dell Perc controllers with the Ctrl R bios: http://community.spiceworks.com/how_to/show/8781-configuring-virtual-disks-on-a-perc-5-6-h700-contro...
